Anti-Rutting Additive (CCI-ARA-6000/8000/10000)

Main Functions of Anti-Rutting Additive: 

• Bonding Effect: During the wet mixing and transportation process, the anti-rutting asphalt mixture additive partially dissolves or swells in the asphalt, forming a bonding effect. This leads to an increase in the softening point temperature, viscosity, and a decrease in the thermal sensitivity, thereby modifying the asphalt.


• Reinforcement Effect: The microcrystalline regions formed by polymers possess considerable stiffness. During the mixing process, these microcrystalline materials uniformly fill the aggregate skeleton, bridging and crosslinking to form a fiber reinforcement effect, thereby enhancing the rut resistance of the asphalt pavement.


• Embedding Effect: The anti-rutting asphalt mixture additive softens temporarily during construction. Subsequently, these particles undergo thermal molding during compaction. This process is equivalent to fine aggregates with high adhesion filling the voids in the aggregate skeleton, increasing the structural framework of the asphalt mixture, and simultaneously reducing the permeability of the formed pavement surface.


• Deformation Recovery Effect: The elastic component of the anti-rutting asphalt mixture additive possesses the function of elastic recovery of the deformed portions of the pavement at higher temperatures, thereby reducing the permanent deformation of the formed asphalt pavement.


Features and Advantages:

• For Transportation: It is granular and easy to transport without using special carrier.

• Storage: It can be stored at room temperature without any special equipment.

• Construction: In the process of mixing, spreading, and rolling, there is no need to make any changes to the equipment.

• Rutting: After adding, the mobility of asphalt mixture is 80% higher than that of matrix asphalt mixture, which indicates that the rutting resistance of asphalt pavement has been greatly improved.

• Fatigue: After adding, the fatigue performance of asphalt mixture is increased by 40%, and the entry resistance of asphalt pavement is enhanced.

• Water Stability: After adding, the freezing-thawing splitting strength of asphalt mixture can reach 97.95%, improving the ability of asphalt pavement to resist water damage.

• Low Temperature: After adding, the maximum bending strain of the mixture is increased by 34%, and the bending strain is increased by 73%. At the same time, the elastic recovery performance of asphalt binder is also greatly enhanced. The variable temperature is 10 ̊C, so it is suitable for preventing temperature shrinkage cracks below 10 ̊C.
